Thanks for the info - bought the control amp but hesitated and decided to try freon with die to find any leak first. What do you know the High pressure hose next to the radiator was leaking really bad. It's easy to put Die in and really hard to change out the Amp so try the Die first and check the hose.  

I am so glad that I found this thread.  I have been having this same issue with my 2000 xterra for the last two summers.  It has been bothering me, but since it would eventually kick in the cold air about 10-20 down the road I just dealt with it.  Well, we finally bought new cars and I'm going to sell the xterra.  I wanted to fix the air before selling it, because I think that would just be wrong to sell it to someone the way it is.  I was afraid this was going to cost me $1,000 or more.  I just ordered the thermo amp and it is being shipping to me.  I will hopefully be able to switch it out this weekend.  I really hope this is the part that I need.  This is the first problem I've had with my xterra and it has over 140,000 miles on it.  I'm so thankful that this might not cost me any more than $50.00 and a little bit of time.  Thanks for all the information on this thread.  I may be back if this part doesn't fix anything.  

First, thanks for the installation guide for the TCA.  Changed that out, didn't fix the hot air.

Problem: Initially, intermittent cool, warm air. No clicking on/off of compressor like others had. Then, a week later, only hot air.  Also, hear hissing sound during this transition. Also, would hear air blowing out from near glove box, but that would go away.  Pressure in air flow was intermittently reduced at times.  Now, just warm/hot air coming out, no rapid on/off clicking, and good pressure flow.

Is this due to a leak somewhere?

Pressure hose?

Will I need to recharge?

Thanks in advance for any tips on this.

At least have experience changing TCA and knowing where to change out filters for cabin air.
